There was a time romances in games were a nice gimmick. Now seeing the amount of resources they take for such a minimal amount of content per playthrough... I'm really starting to resent them.
Back to the question of the topic: Preferably none for my 'real' playthrough, maybe Karlach if she is well written. If I do multiple playthroughs I might just engage in romances to see how Larian handled them.
I wouldent call Yen, Triss, and many others "minimal content"
